Prior studies have largely provided cross-sectional snapshots of chair characteristics, limiting understanding of how chair profiles have evolved over time.

Demographic characteristics, educational history, scholarly productivity, and institutional familiarity prior to chair appointment were collected from publicly available sources, Scopus, National Institutes of Health (NIH) RePORTER (Research Portfolio Online Reporting Tools Expenditures and Results), and Google Patents. Chairs were stratified into quartiles based on appointment year, and temporal trends were assessed using chi-square and Kruskal-Wallis tests.

The median age at appointment increased from 46 to 51 years from the earliest to the most recent quartile (p &lt; 0.001), while female representation rose from 0% to 10.4% (p = 0.001).
